Universal thermal compound for CPUs and GPUs

ARCTIC MX-4 thermal paste comes in a 20 g syringe and is designed for processors and graphics cards in PCs, PlayStation 4 and Xbox consoles. The carbon microparticle formula fills microscopic surface cavities to transfer heat away from the die quickly. It is metal-free and non-electrically conductive, so there is no risk of short circuits on surrounding components.

Consistent formula with simple syringe application

The manufacturer states the MX-4 composition has remained unchanged across packaging revisions, giving a reliable reference for repeat builds. Its consistency is tuned for easy spreading, even for first-time users, and a video guide is referenced to help avoid air pockets. The 20 g volume covers multiple applications on standard desktop sockets and GPU dies.

Non-conductive paste with finite pump-out life

Because the compound contains no metal particles, it eliminates capacitive and conductive hazards near exposed PCB traces. Like all non-liquid-metal pastes, it will gradually dry and lose efficiency over long periods, requiring eventual re-application for sustained thermal performance. The 20 g quantity sets a hard limit on the number of full reseats possible before a new tube is needed.

Questions about this item

Does the 20 g syringe of MX-4 contain enough paste for multiple CPU and GPU applications?

Yes, the 20 g volume typically covers many installations on processors and graphics cards.

What mounting pressure or spreader is required for the carbon microparticle compound to fill microscopic surface dents?

Standard cooler mounting pressure is sufficient; the paste consistency spreads under the heatsink without extra tools.

How do I apply MX-4 to avoid air pockets between the die and the cold plate?

Place a small pea-sized dot in the centre and let the cooler pressure spread it evenly across the surface.
